The SLAC has a 3km long underground linear accelerator which is the longest linear accelerator in the world and claimed to be the world’s straightest object. The building above ground on top of the accelerator, the “klystron gallery”, is the longest building in the United States. The Advanced Photon Source (APS) at Argonne National Laboratory in Illinois is another US based lab with a linear accelerator but this one uses a Synchrotron. A synchrotron is a circular…
